An active work zone getting good lighting doesn't automatically mean the site's perimeter is covered — and a dark boundary fence is both a safety gap and a genuine theft-deterrence gap on a site holding valuable materials and equipment overnight.
Task lighting illuminates active work; perimeter lighting is about visibility and deterrence along a site's boundary, particularly overnight when the site isn't actively worked but materials and equipment remain on-site. These are distinct lighting needs, covered in our broader night construction safety guide.
A visibly lit perimeter is a genuine, well-understood deterrent against unauthorized access and theft, separate from any camera or guard presence — visibility itself changes the calculation for anyone considering accessing an unattended site.
Perimeter lighting works well alongside temporary CCTV coverage — see our temporary CCTV power guide for how a device power platform supports camera monitoring at the same boundary positions.
A full site perimeter often runs longer than any single light can cover well — a small number of high-output towers positioned at intervals along the boundary is generally more practical than trying to achieve uniform coverage with many smaller units.
A site's perimeter and material storage areas shift as construction progresses — lighting that repositions easily keeps pace with where materials and equipment actually are, rather than staying fixed to an early-phase layout.
The LI-500's high output suits covering long perimeter stretches from fewer positions; the LI-300 suits repositioning as material storage areas and site boundaries shift through a project.

Yes — lighting and temporary camera monitoring complement each other at the same boundary positions, rather than one substituting for the other.
